I'm calculating spectrum amplitudes from the result of a
complex FFT. ( sqrt(re^2 + im^2) )
Does anyone know of any optimized code or libs for doing this
across large, 8192+, arrays?
Are there any such utility routines in CoreAudio?
The code you're searching for has a big dependency with the
accuracy you need for your spectrum amplitudes estimation :
- if it is for graphic purpose you can roughly approximate it
- it it is for dsp purpose, you'll have to evaluate the error
propagation next in your dsp process
What is it for ?
